I recently bought a crossbow and wanted a quick way to mount it and the bolts to a wall. I used #8 3" screws to attach the thick parts to the wall. Works well and does what I needed.
The bolt supports won't allow broad heads. Holes are 10mm in diameter. The wall hook is 40mm in width.
No supports needed to print. I did the hook in 100% fill, but all other items at 20%
